Louvers

[hauto]

This group always seems to have the answer.I looking for a shop or some one that can louver a airbox cover as pictured.

 any direction will be appreciated. Thanks Joe

Any competent machine shop should be able to do that.  Drop by a couple, side cover in hand, and see what they say.  If they cant, Im sure they know someone who can.

Good luck!

Good luck. It takes a louver press, and a different die set for each size of louver. *Maybe* a dedicated hot rod shop. You "can" do louvers by hand by drilling 1/16" diameter holes at the end of each louver, and cutting a straight line between them with a special chisel. Then, the raised part can be done with a punch for each end. Not for the uninitiated in sheet metal work. 
The louvers in the boot cowl of the Great Lakes I built was done this way..

It isn't black magic or a "lost art".  It just needs to be approached properly. 

Serious equipment like a dedicated louver press or a pullmax will simplify the process.  Without such, you can do a lot with simple tools OR will need to pay a fair price to have it done.  Email sent.

A quick look at the side cover looks like a solid piece of aluminum with lines cut through. Thicker  type fins vs louvers.  If what I'm describing is the actual case then a router would do the trick.
